“…It is also possible to restrict the convergence test to the unknowns, which are fewer than the ones, but these are not the unknowns of interest. To study the convergence of the RBCI procedure, let us derive from the first matrix equation in (28) and substitute in the second one to obtain (30) where is a square matrix of order given by (31) It is clear that the RBCI procedure (28) converges when the spectral radius of matrix is less than one. Obviously, depends on both and the placement of .…”

A new numerical method, called Robin boundary condition iteration (RBCI), is proposed for the finite-element (FE) solution of electromagnetic scattering problems in open boundary domains. The unbounded domain is truncated to a bounded one by means of a fictitious boundary that contains the scatterer and on which a suitable nonhomogeneous Robin (mixed) boundary condition is assumed for the Helmholtz equation in the bounded domain. The Robin condition is expressed by means of an integral formula (the second Green identity) in terms of the field in the interior of the bounded domain, with the integration surface being a surface strictly enclosed by the truncation boundary. The discretized differential and integral equations are then coupled together to solve the problem. The formulation is completely immune from the well-known interior resonance problems. A simple and effective iterative solving scheme is described. Examples are also provided to validate RBCI and compare it with other methods. Index Terms-Finite-element (FE) methods, integral equations, scattering.

“…For each block generated by the CBFM, the FEM is used to analyze the volume meshes and MoM [7,8] is uesd to analyze the boundary and external sections. Next, enforcing the continuity of tangential fields on the joint face can make the two methods coupled [6]. By solving the coupled matrix, a series of new CBFs are obtained.…”

An efficient hybrid technique that combines the characteristic basis function method (CBFM) and the finite element method (FEM) is presented for analyzing the scattering of large-scale array structures which may be dielectrics or metal objects. By utilizing the hybrid method, the whole array structures are divided into several blocks, and a set of the new characteristic basis functions (CBFs) independent of the incidence are generated. Furthermore, the singular value decomposition (SVD) leads to a significant reduced matrix. Numerical results are provided to demonstrate the efficiency and accuracy of the method. Index Terms-CBFM, FEM, electromagnetic scattering, radar cross section (RCS).

SUMMARYMeasurement and modeling of the undesired electromagnetic waves (electromagnetic noise) from electronic devices play an important role in the understanding of EMI problems and in establishing design techniques. One of the methods of analysis of the EMI problems of electronic devices is the measurement of the common mode current flowing in the cables connected to the electronic devices. This paper reviews the measurement of the common mode current on printed circuit boards (PCB) and discusses results related to the EMI problems of PCB. FDTD modeling of the common mode current by traces placed near the PCB edge and suppression of the common mode current by the guard band are described.
